The present invention relates to a heat treatment pack capable of heat-treating a predetermined content in a sealed state, and in particular, a content to be heat-treated and a constituent element (heating element) necessary for the heat treatment are integrated into a unit. Heat treated packs.

BACKGROUND ART Conventionally, a heat treatment package for heat treating contents and a packaged food product in which food is stored are known (for example, refer to Patent Document 1). Such a heat treatment package and packaged food can be heat-treated in a microwave oven or the like while keeping the contents (food) in a sealed state, and when the internal pressure rises due to heating, a predetermined position is opened to release the pressure. By doing so, it is possible to prevent the package from bursting.

However, such a heat treatment package and packaged food cannot be used in a situation where a heating device such as a microwave oven cannot be used.

Therefore, in order to easily heat foods and the like even in a situation where a heating device such as a microwave oven cannot be used, such as during camping outdoors or during emergency evacuation in the event of a disaster, the applicant has to react with water. A heat treatment pack (steam pack (registered trademark)) composed of a heat generating agent that heats up in the air and a heating bag with a chuck that can accommodate this heat generating agent together with water and that has a steam port that opens due to the steam pressure during heat generation (See Non-Patent Document 1).

However, in the heat treatment pack as disclosed in Non-Patent Document 1, when used, the exothermic agent, the reaction water for reacting with the exothermic agent, and the food to be heated are individually chucked and heated. It takes time to put it in the bag.

In addition, considering the time of a disaster, it is difficult to secure clean reaction water because the lifeline is broken, and if sewage water is used as reaction water, there will be hygienic problems such as food contamination. Concerns are needed, especially for infants and the elderly who have low immunity.

The present invention has been made focusing on the above-mentioned problems, and can be stored as it is for a disaster or the like, and can be easily heat treated even in an environment where a heating device such as a microwave oven cannot be used, and in a hygienic manner. Also aims to provide an excellent heat treated pack.

In order to achieve the above-mentioned object, the heat treatment pack of the present invention has first and second compartments partitioned by a peeling section that peels off under the action of a predetermined pressure, and these compartments are the peeling sections. A heating element container that communicates with each other by peeling off parts, and a content container that is detachably connected to the heating element container and that contains the content to be heated. An exothermic agent that reacts with water to generate heat is contained in the first compartment, and reaction water for reacting with the exothermic agent is contained in the second compartment of the heating element container. It is characterized by

According to the above configuration, a predetermined pressure (or impact) is exerted on the peeling portion by, for example, manually tapping or pressing the heating element container from the outside in the second compartment where reaction water is contained. Then, the peeling portion separates, the first compartment and the second compartment communicate with each other, and the reaction water in the second compartment flows into the first compartment. Then, the reaction water that has flowed in reacts with the exothermic agent contained in the first compartment, so that the exothermic agent generates heat. Therefore, at this stage, if the contents container is overlaid on the heating element container or the contents container is housed together with the heating element container in another bag such as a heat insulating bag, the heat generating agent The contents in the contents container can be heated by the heat generated by. After that, when the heating process of the contents is completed, the contents container (if it is still connected to the heating element container) may be removed from the heating element container.

As described above, the heat treatment pack having the above-described configuration includes the contents to be heat-treated (contents container) and the components necessary for the heat treatment (heating element container containing a heating agent and reaction water as heating elements). Is integrated into a unit, and it is possible to obtain the heat-treated contents with one of them, so that it can be stocked as it is, and even in an environment where heating equipment such as a microwave oven cannot be used, with a heating agent, The content can be easily heat-treated by simply applying pressure from the outside to the peeling portion without the need to separately put the reaction water and the content to be heated in the heating equipment. Further, since the reaction water is secured in advance in the heating element container, it is not necessary to use sewage or the like as reaction water in a bad environment. Is also excellent.

In the above-mentioned configuration, as the contents, in addition to foods and beverages (liquid foods such as water, soup, and rice porridge), non-food products such as drug solutions (drug solutions such as dialysate) and adhesives may also be mentioned. it can. The exothermic agent may be lime, for example, and the heating element container and/or the content container may be transparent, translucent or opaque.

In addition, in the above-mentioned configuration, it is preferable that the contents container is connected to the heating element container so that the contents container can be folded back so as to be superposed on the heating element container. By doing so, the content container can be superposed on the heating element container while being connected to the heating element container, and rapid heating of the content container by the heating element container can be realized. Further, in this way, if the contents container is connected to the heating element container so that it can be folded back so as to be superposed on the heating element container, it can be folded and compact when the heat treatment pack is stored ( Since it can be reduced in volume), it is also excellent in storability.

Further, in the above structure, it is preferable that the heating element container has an easily-openable seal portion for releasing an internal pressure that rises during the heat treatment accompanied by heat generation of the heat generating agent. Generally, during the heat treatment accompanied by heat generation of the exothermic agent, the reaction water evaporates to generate steam, and the pressure in the heating element housing increases due to the steam pressure. If it can be escaped to, it is possible to prevent the heating element container from bursting during the heat treatment.

Further, in the above configuration, the heating element container may have an opening that allows the first compartment and/or the second compartment to be opened and closed. With such a configuration, the exothermic agent and/or the reaction water can be easily inserted into each compartment through the opening when the heat treatment pack is manufactured, and the exothermic agent and/or the reaction water can be inserted through the opening in the storage state before use. It is possible to take out or observe the water to confirm their storage condition, and to replace them in some cases, and further, to remove the exothermic agent and/or the reaction water from the heating element container through the opening after the heat treatment and Can also be individually discarded.

In this case, the exothermic agent and the reaction water may be directly contained in the first and second compartments as they are, but as an example, the exothermic agent is contained in a water-permeable exothermic agent container, for example, a nonwoven fabric. May be accommodated in the first compartment in a closed state, and the reaction water may be accommodated in the second compartment while being accommodated in a container that is opened under the action of a predetermined pressure to release the reaction water to the outside. It may be housed in a room. This makes it easy to handle the exothermic agent and the reaction water.

Further, in the above structure, it is preferable that the contents container has a spout (for example, a spout) for pouring out the contents. By providing such a spout, it becomes easy to pour out the contents from the contents container.

According to the present invention, a heat treatment pack that can be stored as it is in case of a disaster or the like, can be easily heat treated even in an environment where heating equipment such as a microwave oven cannot be used, and is excellent in hygiene.

It is a front view showing the concept of the heat treatment pack concerning one embodiment of the present invention.

An embodiment of the heat treatment pack 1 according to the present invention will be described below with reference to FIG.
As shown in FIG. 1, the heat treatment pack 1 according to the present embodiment has first and second compartments S1 and S2 that are partitioned by a peeling portion (easy peeling seal portion) 8b that peels off under the action of a predetermined pressure. And a bag-shaped content container 6 that is detachably connected to the heating element container 8 and that stores a content 10 to be heated. In this case, in the first compartment S1 of the heating element container 8, a heating agent 12 that reacts with water to generate heat is contained as a heating element, and the second compartment S2 of the heating element container 8 is contained. The reaction water 14 for reacting with the exothermic agent 12 is housed in. The contents 10 contained in the contents container 6 include foods and drinks containing liquid foods such as soups and porridges, and non-foods such as drug solutions (medical solutions such as dialysate) and adhesives. You can also list the items.

The heating element container 8 may be transparent, semi-transparent, or opaque, and a pair of sheet-shaped members are overlapped and welded to the periphery, or the sheet-shaped member is bent and the side portions are welded to form a bag shape. Formed in. The heating element housing 8 is formed of, for example, a heat-resistant plastic material (plastic film). Specific examples of such plastic materials include polyolefins such as polyethylene and polypropylene; halogenated polyolefins such as polyvinylidene chloride and polyvinylidene fluoride; polyvinyl alcohol; nylon 6, nylon 6,6, polymetaxylylene adipamide and the like. Polyamide: Polyester such as polyethylene terephthalate, polyethylene naphthalate, polybutylene terephthalate, polybutylene naphthalate; Polyacrylic ester such as methyl poly(meth)acrylate, ethyl poly(meth)acrylate, butyl poly(meth)acrylate And a copolymer of monomers forming them; In addition, "(meth)acryl" means methacryl or acryl.

Specific examples of polyethylene include linear low-density polyethylene, high-pressure low-density polyethylene, high-density polyethylene, and metallocene-based polyethylene. Specific examples of polypropylene include a homopolymer of propylene and a random or block copolymer of propylene and ethylene or 1-butene.

The plastic film may be a single layer, or may be laminated in two or more layers by coextrusion or the like. For example, the plastic film preferably comprises a base material layer and an easy open layer, and may further have another layer between the base material layer and the easy open layer. The plastic film may be a gas barrier composite film provided with an inorganic oxide thin film such as aluminum oxide or silicon oxide. This composite film can be obtained by heating and vaporizing a simple substance or a mixture of aluminum oxide and silicon oxide under vacuum and depositing it on the surface of the film.

Further, the heating element container 8 has an easily openable seal portion 8a for releasing the internal pressure that rises during the heat treatment accompanied by the heat generation of the exothermic agent 12. Such an easily-openable seal portion 8a can be formed by, for example, a palm-sealing joint portion in which the same surface sides of the plastic films are brought into contact with each other and joined in a palm-shape by heat sealing.

In the present embodiment, the easy-open seal portion 8a is formed so as to be located at, for example, the edge of the heating element container 8 or the vicinity of the edge (in the case of the illustrated example), and the heating element container is subjected to the heat treatment. 8 has an easy-open property that allows the pressure to escape when the internal pressure rises. Specifically, the easily-openable seal portion 8a is provided with a pair of plastic film parts constituting the easily-openable seal portion 8a of the plastic film forming the heating element container 8 as required by an easy open tape (not shown). ) Is inserted and heat-sealed. The position of the easy-open seal part 8a in the heating element container 8 is not limited to the illustrated position. If the internal pressure of the heating element container 8 rises due to the heat treatment and the pressure can be released, the position of the easy-open seal part 8a can be set arbitrarily.

More specifically, the easy-open seal portion 8a preferably has a heat seal strength of 1200 g/15 mm or less in a 90° C. atmosphere, and more preferably 800 g/15 mm or less. The heat-seal strength of the easy-open seal part 8a in a 90° C. atmosphere may be 0 g/15 mm, but is preferably 100 g/15 mm or more. The heat-sealing strength is a value measured in an atmosphere of 90° C. according to JIS Z0238 “Testing method for sealed soft packaging bag”.

Further, the easy-open seal part 8a may be a complete seal or an easy open at room temperature. The heat-sealing strength of the easy-open seal part 8a in a normal temperature atmosphere is preferably 150 to 2000 g/15 mm, more preferably 300 to 1500 g/15 mm. The heat-sealing strength in a room temperature atmosphere is a value measured in a room temperature (23° C. 65% RH) atmosphere in accordance with JIS Z0238 “Test method for sealed flexible packaging bag”.

As an example of complete sealing at room temperature and heat sealing strength of 1200 g/15 mm or less in a 90° C. atmosphere, a polyolefin such as a melting point of 120° C. or less (preferably 110° C. or less) is used as the sealant of the easy-open seal portion 8a. This can be realized by using polyethylene or polypropylene having a melting point of 140° C. or lower (preferably 130° C. or lower) and using a sealant having a melting point of 10° C. or higher higher than this as the sealant for the other part. The melting point is a value measured based on ASTM2117.

In addition, in the present embodiment, a plurality of through holes (not shown) arranged in the direction perpendicular to the width direction of the heat seal forming the easily openable seal portion 8a is provided in one of the plastic films forming the easily openable seal portion 8a. No.) is preferably provided. By doing so, when the internal pressure of the heating element container 8 rises due to heating, the easy-open seal portion 8a vaporizes and bursts at the position of the through hole before opening across the entire width of the heat seal. Sound is less likely to occur. Further, water vapor can be released to the extent that the heating element container 8 does not burst, and it is possible to prevent the internal pressure from dropping more than necessary and the contents 10 from jumping out.

The peeling portion (easy peeling seal portion) 8b for partitioning the compartments S1 and S2 described above also has a predetermined heat seal strength (peeling strength) such that it is easy peel open at room temperature, similar to the easy-open seal portion 8a. May be formed as long as it can be separated from each other when the predetermined pressure is applied to allow the compartments S1 and S2 to communicate with each other.

The content container 6 that is detachably connected to the heating element container 8 configured as described above may be similarly formed of a plastic material (for example, a plastic film). The element container 8 and the content container 6 are integrally formed by a plastic film, and the heating element container 8 and the content container 6 are completely separated only by heat sealing the plastic films to each other, and the heat Perforations (or notches or magic cuts) 30 may be provided in the middle portion of the seal in the width direction so that the heating element container 8 and the contents container 6 can be separated (removable).

By doing so, the content container 6 can be folded back so as to be superposed on the heating element container 8, and the removable and foldable connection of the content container 6 to the heating element container 8. Can be realized. However, the form of the removable and foldable connection of the content container 6 to the heating element container 8 is not limited to this. Of course, the content container 6 may be formed separately from the heating element container 8 as, for example, a self-standing bag, and the content container 6 and the heating element container 8 may be detachably connected. Further, the contents container 6 of the present embodiment has a spout 20 (for example, a spout) 20 for pouring the contents 10 on one side, but without providing such a spout, the sewing machine is not provided. It may be configured such that eyes or the like are formed and cut.

Further, in the present embodiment, the heating element container 8 may have an opening that allows the first compartment S1 and/or the second compartment S2 to be opened and closed. For example, in one aspect of the present embodiment, openings 40 and 41 are provided on the side portion of the heating element container 8 so as to correspond to the first compartment S1 and the second compartment S2, respectively. Such openings 40 and 41 may be formed by an openable/closable seal part having the same configuration as the easily-openable seal part 8a described above, but may be formed by a notch or a chuck. Of course, such openings 40 and 41 do not have to exist.

Further, the exothermic agent 12 and the reaction water 14 contained in the first and second compartments S1 and S2 may be directly contained in the first and second compartments S1 and S2 as they are. As an example, the exothermic agent 12 may be accommodated in the first compartment S1 while being accommodated in the water-permeable exothermic agent container 2, for example, in a bag made of nonwoven fabric. Further, the reaction water 14 may be stored in the second compartment S2 in a state of being stored in a bag-shaped storage body that is opened under the action of a predetermined pressure to release the reaction water 14 to the outside. By doing so, the exothermic agent 12 and the reaction water 14 can be easily handled.

In the present embodiment, the exothermic agent 12 is 100% lime, unlike the conventional one that contains a metal to generate hydrogen gas, and its heat generation is controlled by, for example, the basis weight of the nonwoven fabric.

According to the heat treatment pack 1 of the present embodiment configured as described above, the heating element container 8 is tapped or pressed from the outside, for example, by hand at the portion of the second compartment S2 in which the reaction water 14 is stored. When a predetermined pressure (or impact) is applied to the peeling section 8b by, for example, the peeling section 8b peels and the first compartment S1 and the second compartment S2 communicate with each other, and the second compartment The reaction water 14 in S2 flows into the first compartment S1. Then, the reaction water 14 that has flowed in reacts with the exothermic agent 12 contained in the first compartment S1, so that the exothermic agent 12 generates heat. Therefore, at this stage, the contents container 6 is superposed on the heating element container 8 by bending or removing it by using the perforations 30, or the contents container 6 together with the heating element container 8 are stacked. If it is housed in another bag such as a heat retaining bag, the contents 10 in the contents container 6 can be heated by the heat generated by the exothermic agent 12. After that, when the heating process of the contents 10 is completed, the contents container 6 (if still connected to the heating element container 8) may be removed from the heating element container 8.

As described above, the heat treatment pack 1 of the present embodiment includes the content 10 (the content container 6) to be heat treated and the components necessary for the heat treatment (the heating agent 12 and the reaction water 14 as the heating elements). The heating element container 8) is integrated into a unit, and the heat-treated contents 10 can be obtained as it is, so that it can be stored as it is in case of a disaster or the like. Further, the contents 10 can be simply applied to the peeling portion 8b from the outside without the need to separately put the exothermic agent, the reaction water, and the contents to be heated in the heating element container. Can be easily heat treated. Further, since the reaction water 14 is secured in the heating element container 8 in advance, it is not necessary to use sewage or the like as reaction water in a bad environment, and therefore the contents 10 are not contaminated. Good and hygienic.

Further, in the present embodiment, since the content container 6 can be overlapped on the heating element container 8 while being connected to the heating element container 8, the content container 6 by the heating element container 8 can be stacked. The rapid heating of can be realized. Further, since the contents container 6 is connected to the heating element container 8 so that it can be folded back so as to be superposed on the heating element container 8, the heat treatment pack 1 can be folded and compact when stored. (Can be reduced in volume) and has excellent storability.

In addition, since the heating element container 8 of the present embodiment has the easily-openable seal portion 8a, the reaction water 14 evaporates and vapor is generated during the heat treatment accompanied by the heat generation of the exothermic agent 12. Even if the pressure inside the heating element container 8 rises, the increased pressure can be released to the outside by the easy-open seal portion 8a, and the rupture of the heating element container 8 can be prevented during the heat treatment.

In addition, the heating element container 8 of the present embodiment has the openings 40 and 41 that allow the first compartment and/or the second compartments S1 and S2 to be opened and closed. At the time of manufacturing, the exothermic agent 12 and/or the reaction water 14 can be easily inserted into the compartments S1 and S2 through the openings 40 and 41, and the exothermic agent 12 and the reaction water 14 can be inserted through the openings 40 and 41 in a storage state before use. It is also possible to take out or observe the reaction water 14 to confirm the storage state thereof and to exchange them as the case may be. Furthermore, after the heat treatment, the exothermic agent 12 and/or the reaction water 14 can be taken out from the heating element container 8 through the openings 40 and 41 and can be individually discarded.

Further, in the present embodiment, the content container 6 has the spout 20 (for example, a spout) for pouring out the content, so that the content 10 can be easily dispensed from the content container 6. Become.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. For example, in the above-described embodiment, the exothermic agent is 100% lime, but the component material forming the exothermic agent is not limited to this. In addition, the materials for forming the heating element container and the content container are not limited to those in the above-described embodiment, and can be set arbitrarily. Further, the positions of the easy-open seal portion and the opening portion in the heating element container can be set arbitrarily. Furthermore, the method of dividing the compartments of the heating element container can be modified appropriately.
